Sangma confident of Mamata's support

"I am constantly in touch with her. I am going to meet her in the next couple of days. I am very much hopeful of her support," Sangma told a news channel.

Even as the numbers favour United Progressive Alliance (UPA) candidate Pranab Mukherjee, Sangma said: "The election is governed by Article 55 and the Article 55 is clear that the election shall be by a secret ballot. The question of numbers does not arise at all at this stage."

"Secret ballot means conscience vote. I depend on the conscience vote and I believe in the conscience vote," he said.

On division among UPA and Left front, Sangma said: "There is a split in almost all political parties. That shows this election is a serious election. It's not as smooth as the Congress is claiming it to be. There is a split because people are giving serious thought to it. This is a welcome development."

"Pranab Mukherjee is also not getting an undivided UPA. Mamata Banerjee is a part of UPA and she is not supporting Pranab Mukherjee as yet."

The Bharatiya Janata Party (BJP) Thursday announced its support to Sangma.
